On March 17, 2013Göran Strand created this time-lapse video from images of the Aurora Borealis as seen from Östersund, Sweden.

from the page
This video shows what happened on Mars 17 when an CME (Coronal Mass Ejection) hit Earths magnetic field. Two days earlier, sunspot AR1692 had produced a M1-class solar flare that resulted in the CME that hit Earth.

This time lapse shows what happened during four hours over Östersund here in Sweden, between 19:20 and 23:35 UT.

The time lapse consists of 2464 raw images for a total data amount of 30Gb. The photo of the Sun is a hydrogen alpha mosaic I’ve made from 10 images that was captured on Mars 16. Total of 10 Gb data. So all in all this movie contains over 40Gb of data that I’ve been processing over the last 5 days. Hope you enjoy it.
